摘要: An optoelectronic sensor for real time leakage current monitoring on high-voltage (13.8 kV) power line insulators was developed. The drives an ultra-bright green LED producing AM light signal. optically intensity-encoded signal is coupled to a 1-mm plastic optical fiber and transmitted from the high potential measurement point Remote Unit in ground potential. After demodulation, values are concentrated data logger sent remote station 150 km away by GPRS technology.
